Federal Premium, Vital Shok, 12 Gauge 3, 4 Buck, 2oz, Buckshot, 41 Pellets, 5 Round Box P1584B Buckshot can get dismissed as the stuff of simple scatterguns, but Federal engineers these shotshells to provide the same precision performance as all of Federal's other loads. Federal Premium Vital-Shok Buckshot uses copper-plated pellets to produce tight patterns and great downrange energy. It also puts more hits on target for impressive stopping power on predators, hogs and deer.
